Opportunity ready to roll

This image shows a simulated Opportunity about to descend into Victoria Crater via the rock-paved slopes of an alcove dubbed Duck Bay. Inside the crater, the rover examined the deeper, older rocks that harbored clues to Mars' wet past. Duck Bay has slopes of about 15 to 20 degrees and exposed bedrock, which made it the safest site for entry.
